LEFTIES historically have had a tendency to be left behind. Recently being left-handed was still considered abnormal. Of course, we now know there’s nothing wrong with being left-handed. And it does come with certain differences.

Lefties may be quicker thinkers. Lefties may be able to use both sides of the brain more easily and efficiently. According to a study published in 2006, lefties tend to have faster connections between the right and left hemispheres (半球) of the brain, which leads to quicker information processing — a cognitive (认知的) advantage that could benefit them in things like video games and sports.

Lefties have the upper hand in some sports. While less than 15 percent of the general population is left-handed, 25 percent of Major League baseball players are lefties. Why? It may be because they tend to have faster reaction times. But there’s another reason. Studies have found that lefties seem to have a real advantage in interactive sports, such as boxing and baseball — but this advantage doesn’t extend to non-interactive sports, like gymnastics and diving.

Lefties may be more creative thinkers. Many studies have suggested a link between left-handedness and creativity. Some research has found that lefties are better at abstract thinking. However, it’s important to find that studies show relation, not its causes and effects, so it takes time to prove the findings.

1. What does the underlined word “them” in Paragraph 2 refer to?
A.Thinkers.B.Connections.C.Sports.D.Lefties.
2. Which of the following could lefties do best?
A.Baseball.B.Diving.C.Running.D.Gymnastics.
3. What does the author mean in the last paragraph?
A.Studies have suggested lefties are more creative thinkers.
B.There is a clear link between left-handedness and creativity.
C.Much needs to be done to prove lefties are more creative thinkers.
D.All the research has found that lefties are better at abstract thinking.
4. Where is this text most likely from?

文章大意:本文是一篇说明文。文章主要介绍了关于小睡的相关研究。

【推荐1】Napping (小睡) may be part of life for most of us. However, some countries where daytime naps have long been part of the culture, such as Spain, now discourage the habit. Meanwhile, some companies in the US now promote napping as a way to boost productivity. “It’s important to try to reveal the biological pathways that contribute to the reason why we nap,” says Dashti from Harvard Medical School.

Previously, co-senior author Richa Sexena at Massachusett s General Hospital (MGH) and his colleagues used many databases of genetic and lifestyle information to study other aspects of sleep. To gain a better understanding of the genetics of napping, they performed a genome (基因组)-wide association study (GWAS), which includes rapid scanning of complete sets of DNA of a large number of people.

For this study, the researchers used data from the UK Biobank, which includes genetic information from 452,633 people. All the participants were asked to classify their naps during the day as “never/ rarely”, “sometimes” or “usually”. The GWAS identified 123 regions in the human genome connected with daytime napping. Then the participants wore activity monitors called accelerometers, which can provide data about daytime napping. This data also showed that the self-reports about napping were accurate.

Several other features of this study support its results. For example, the researchers obtained similar findings in an analysis of the genomes of 541,333 people collected by 23andMe, a consumer genetic-testing company. Also, a significant number of the genes near or at regions identified by the GWAS are already known to play a role in sleep.

The team also identified at least three potential mechanisms (机制) that promote napping. Some people need more shut-eye than others. A daytime nap can help make up for poor-quality sleep the night before. People who rise early may “catch up” on sleep with a nap. “This tells us that daytime napping is biologically driven and not just an environmental or behavioral choice,” says Dashti. Some of these mechanisms are linked to health concerns, such as a large waistline and increased blood pressure, though more research on those associations is needed.

1. What did the researchers at MGH focus on in their new study?
A.The causes of long napping time.
B.The benefits of napping frequently.
C.The reasons behind the napping habit.
D.The genes contributing to poor sleeping quality.
2. What can we know from the text?
A.The subjects of the GWAS came from 123 regions.
B.Activity monitors were used to ensure reliability of the results.
C.Researchers are looking for more genes that can play a role in sleep.
D.American companies encourage nappíng to make people feel at ease.
3. According to Dashti, what will the researchers study next?
A.The ways to help people improve their sleep quality.
B.The causes of and solutions to some health concerns.
C.The impact of environment on people’s napping choice.
D.The connection between some health problems and the mechanisms.
4. Which of the following can be the best title for the text?
A.Health issues caused by daytime napping.
B.Napping considered to be an essential habit.
C.Researchers working hard to promote napping.
D.Biological factors playing a role in daytime napping.

【推荐2】Cover your mouth when you cough, wash your hands… don’t say bad things about math. Researchers have known for years that a fear of math can be contagious. They’ve shown that children can pick up negative attitudes about math from teachers. Now they’ve found another source of “math anxiety”: parents.

The researchers asked parents to rate how anxious they would feel in different situations involving math. They also assessed their children’s math ability and math anxiety. Kids whose parents were anxious about math learned less math and were more likely to become nervous about math themselves. But they only “caught” that anxiety if their parents had frequently tried to help with their homework. “Inadvertently,” Mark Ashcraft says, “when those parents are trying to help with homework, they’re conveying their own bad attitudes about math to their children.”

Those children also seemed to learn less math in school. Kids whose parents were anxious about math — and who had helped them with their homework—did not perform as well on the tests as did those who had not been exposed to math anxiety.

“I was sympathetic to the parents and their kids. I was always very nervous about math, not only taking tests, but also learning new concepts. I really tried to avoid math,” Erin Maloney says. It was only after she studied statistics in graduate school and saw how it could be applied to her passion—psychology—that she started to enjoy math.

Parents with math anxiety shouldn’t avoid supporting their kids as they work on math assignments, though. Instead, they should look for ways to have fun with math, like playing math-based games. And if parents feel unsure about their own abilities, they should a- void talking about it. They instead should try to put a positive spin on math.

Helping kids with schoolwork requires more than just going over facts and concepts, Maloney notes. “It’s also attitude,” she says. And their attitude, she says, can have a surprisingly big impact. If parents can’t figure out a math problem, they shouldn’t get frustrated or embarrassed. Rather, they should help their kids plan questions to ask their, teachers.

1. We can infer from the second paragraph that ______.
A.a kid may have the genes of fearing math
B.parents are the first teacher for their kids
C.good intentions may have a bad payoff
D.math is the most fearful subject at school
2. Why did Maloney have mercy on parents and their kids?
A.She knew the use of math in life.
B.She enjoyed learning new math concepts.
C.She had a strong passion for psychology.
D.She had personally experienced math anxiety.
3. What should parents with math anxiety do?
A.Try to make learning math an interesting thing.
B.Avoid helping their kids with math homework.
C.Keep talking about math with their children.
D.Focus on reviewing facts and concepts of math.
4. What might be the most suitable title for the text?
A.Kids’ math ability depends on their parents
B.Parents’ math anxiety can infect kids
C.Math anxiety is a headache to parents and kids
D.Math homework promotes kids, love for math

文章大意:本文是一篇说明文。文章介绍了根据发表在《食品质量与偏好》杂志上的一项新研究,颜色可能会影响挑食者食物的味道。

【推荐3】Color may influence the way food tastes for picky (挑剔的) eaters, according to a new study published in the journal Food Quality and Preference.

Stafford’s research team did an experiment with about 50 participants, who were mostly young adults around 20 years old. The study divided the individuals into picky and non-picky eaters, based on their responses to a certain measure. Both groups then tasted the same snacks served in red, white and blue bowls.

The results showed the color of the bowls influenced how the picky group perceived (感知) the saltiness and desirability of the foods — but did not influence the non-picky group. The picky group thought that the snack served in the red bowl was least desirable and the snack was higher in saltiness in the red and blue bowl — compared with the white bowl.

“Picky eating usually starts in childhood,” Dr. Lama Bazzi said. She explained that if picky eating is not solved properly as a child, it can be developed later into certain eating disorders.

All of this is because of a sense of control and a sense of safety. So when talking about the colors of the bowls in the research study, it probably has to do with what makes that person feel safe, such as what colors are connected with safety. The colors blue, green and purple are considered “safer” colors, while the color red is usually connected with “stop”.

Supermarkets use similar psychology to catch people’s attention. Children’s cups are colorfully designed to entice kids, giving them a sense of safety and making it fun for them to drink something. When advertisers want customers to buy chips or food, the packaging (包装) tends to use warm and inviting colors that remind people of their childhood. Stafford noted that the research is primary, yet the data may help picky eaters to eat various food.

1. What do we know about the experiment?
A.The participants were all young adults.
B.Different snacks were served in different colors of bowls.
C.Colors of the bowl didn’t influence the non-picky group.
D.The picky group thought the snacks in the white bowl saltier.
2. If a picky girl wants to lose weight, what kind of bowl will she use to serve food?
A.Blue bowl.B.Red bowl.C.Green bowl.D.Purple bowl.
3. What does the underlined word “entice” in Paragraph 6 mean?
A.Attract.B.Force.C.Admit.D.Warn.
4. Why do advertisers use warm and inviting colors for packaging?
A.To remind people of their childhood.
B.To give people a sense of safety.
C.To solve people’s eating disorders.
D.To attract people to buy goods.
